1.引言从事电子维修的专业技术人员,基本上都拥有晶体管直流参数测试仪。该仪表不仅可以测试各种二、三极管、可控硅、场效应管的正、反向电压、正向饱和压降、放大倍数、反向漏电流等多种直流参数,还可以测试电解电容、钽电容、独石电容、高压瓷片的耐压值;不仅可以测试压敏电阻的保护电压值,而且可以测试氖泡、霓虹灯管的起辉电压值;有些还可以测试78、79系
1. Introduction Engaged in electronic maintenance of professional and technical personnel, basically have a transistor DC parameter tester. The instrument can not only test a variety of two, transistor, thyristor, FET positive and negative voltage, positive saturation voltage drop, magnification, reverse leakage current and other DC parameters, you can also test the electrolytic capacitor, Tantalum capacitors, monolithic capacitors, high voltage ceramic pressure value; not only can test the varistor voltage protection value, but also to test the neon bulb, neon light of the starting voltage value; some can also test the 78,79 system
